'TELEPEONE.

Application filed. May 21,

This invention relates to more partimilarly to means for supporting and operating; the receivers of such instruments in ,such manner as to leave the hands of the operator free. One of the objects of the invention is to enable this result to be 'secured in a (simple, etlicient and economical manner. A {further and more limited object of the invention is to provide means for nioiinting; a receiver which will enable the latter readily to accommodate the movements of the head of the operator; to employ with such receivers animproved means for establishing or making the circuit including the receiver, said means preferably including; the ordinary receiver hook. A. still further and more limited .obect ot the invention is to enable the foregoing results to be accomplished in a construction winch may on close or encase the receiver wires, not .only tor the purpose of concealment, but to prevent their interference with the operation ,of the instrument.

I accomplish the foregoing objects in and through the construction and arrangement of parts shown in the drawings forming; part hereof, wherein Fig. 1 represents aside elevation of a telephone having my invention applied thereto, some of the varying .positionswhich the receiver may occupy being indicated by dot-and-dash lines; 2 a plan view of the receiver shown in Fig. 1; Fig. 3 a front elevation of the parts shown in Fig. 1, the receiver being broken away;

I Describing the various parts herein by refierence characters, 1 represents the tubular standard, oi ordina y type 1921. Serial No. 471,3?2.

desk telephone, the said standard having the base 2 and carrying the transm tter 43 and which is supported from the transmitter by means of a split or two-partband 6 clamped about the peripheryof the tlzaneniitter, the said band carrying a clamping support for the lower of such arms. The band dis conveniently secured to the transmitter 3 by means of a screw 7 'adjustably connecting the 6 and a rivet 8 extending through the 111, 48 6* at the opposite ends ,01"? the hand sections. The rivet 8, in the preterred t'or m of my invention, not only connects the lugs 6", but secures to the upper of such lugs the clamp for the lower receiver-supporting arm. This clamp, as shown herein, is formed of a strap of sheet metal which is bent to provide a socket 9, carried at the upper ends or" vertical spaced arms 9, the bottoms of said arms lacing bent tov term overlapping}; hottom members 9" and 9. Connecting the vertical arms 9 between the socket 9 and the bottom members 9" and 9, is a bolt 10 which serves to contract the socket or loop 9 about the end of thelower arm of the receiver support. This lower arm is indicated at 11, and is. .prete' ly tubular. The lower end of the arm is ,bent horizontally, as sl iown at 11 to enable it to be fitted within, the socket 9, and the upper end of such lower arm is forked, as indicated at 11* in order to, receive therewithin the lower forked ,end l2. ofthe upper arm 12, both arms heing-connected by means of bolt 13 having therein a wing nut 14, by the adjustment of which the an n 12 may be clamped in any desired angular relation with respect to the lower arm 11.. At its upper end, the arm 12 is provided with a cylind collars and 15 on which bearing a yoke 16 is swiveled. The receiver 5 is ot the short cylindrical type and isrprovided with a pair of trunnions 17 by which it is rota-tably supported within the arms of the yoke 16. It will be evident that the receiver is supported at the ends of the arm 12 in such manner as to have a universal movement.

real bearing, formed between the That is to say, it may be swung at any angle about and with respect to the axis of the upper arm 12; and it may also be swung at any angle with respect to the axis of the trunnions 17, which axis is at right angles to the axis of the arm 12. s

In addition to these moven'ionts of the receiver, the upper arm 12 may be ad-' justed at any desired angle with respectto the lower arm 11, one of such positions being indicated in dot-and-dash lines in Fig. 1; and the arm 11 may also be swung at any desired angle with respect to the socket 9, two of such positions being indicated in full lines and in dot and-dash lines, r spectively, in this same view. In use, the receiver may be left in any position to which it may be adjusted by means of the frictio' bearings 9 and 11, and 11 and 12 as the weight of the receiver and of the arms is insufiieient to bring the center of gravity of the telephone outside of the base 2. The manner of pivoting the arms 11 and 12 enables both arms to be swung about the pivot provided by the socket as an axis as well as allowing the arm 12 to be swung about the axis 13. The first adjustment allows the arms 11 and to be swung in unison while the second allows the eifective distance between the receiver and the socket 9 to be varied.

By making the upper and the lower arms 11 and 12 tubular, the conductors 18 may be led inside of such arms and into the standard 1 and there connected in the usual manner to the receiver switch which is controlled by the hook a. My invention may be used either with or without the ordinary receiver. hen used with the ordinary re ceiver, by removing the latter from the switch hook 4, the circuit including such receiver and the receiver 5 will be closed; and if desired, both receivers may be used, one for each ear of the operator. However, I prefer to dispense with the ordinary receiver, in which case the hook t may still be employed in connection with the receiver circuit. To hold the said hook in circuit opening position, I employ a detent or hook 20 formed at the upper end of a light metal strap 19, said strap being provided with ears 19 whereby it is pivoted upon a bolt 21 mounted in the parallel arms of a spring metal clamp 22 secured about the standard 1 by means of a bolt 23. A spring 24, surrounding the bolt 21 and pressing against the plate 19, forces the detent 20 in a direction to engage the portion 4P of the hook l. Above the hook or detent portion proper, the strap is inclined, as shown at 20, whereby, after the operator has finished with the telephone, the hook may be caught and held circuit-opening position by merely swinging the latter downwardly. The upper end of the inclined portion 20 is engaged by the part l of the hook, and, when the detent is above the part l, the sprin will snap the detent in place.

In Figs. 7 and 8 there is shown a modili cation of my invention in which flat sheet metal arms are employed instead of tubular arms for the support of the receiver. The upper clamping member 6 has secured thereto a plurality of upwardly extendinglugs 25, three such lugs being shown, the spaces between the said lugs receiving the ends of a pair of flat arms 26, said arms being ad justably and frictionally secured to said lugs by a bolt 27. Between the upper or opposite ends of the arms 26 there is inserted the lower or inner end of the arm 28, the upper ends of the arms 26 and the lower or inner end of the arm 28 being connected by means of a bolt 29 having a wing nut thereon. At its upper end, the arm 28 is bent at substantially right angles, as shown at 31, to provide a pivotal seat for the middle of the yoke 1f, the said yoke being rotatably connected to the said seat, as by means of av rivet 32. The receiver 5 is supported in the arms of the yoke 16 in the same manner as is the case with the form of my invention shown in the preceding views.

In Fig. 9 there is shown a modification of my invention, wherein the end 11" of the lower tubular arm 11 is shown as sup ported in a clamp of the type indicated in connection with Figs. 1-6 inclusive, the said clamp, however, being mounted upon a bracket 33 which is secured to the transmitter 3 by means of an arcuate base 34; and screws 35.

In Figs. 10-12 inclusive, there is shown a still further modification of my invention in which the ordinary receiver 36 is shown as supported upon the hook The receiver 5 in this case is mounted on an outer arm 37 which is substantially identical with the arm 12. The lower or inner end of the arm 37 is forked and flattened, as indicated at 3'7, being formed in the same manner as the like end 12 of the arm 12. The cooperating arm 38 is substantially identical with the arm 11 in Fig. 1, but, instead of being carried by the band 6, is pivotally Secured to the bolt 39 by which the transmitter is pivoted upon the top of the standard. For this purpose, the inner end of the tube 38 is partly cut off, leaving a projecting strip 40 which may be bent to shape and having a perforation therethrough for the shank of the bolt 39. The arm 38 is bent in such shape that it extends across the projecting lugs 6 of the two sections of the band 6.

At its outer end, the arm 38 is cut out or forked and flattened at 38, in substantially the same manner as the arm 12 (shown in Fig. 2), thereby to receive the cones )onding parts 37 of the lower or inner on of the arm 37. Then, a short reinforcing tube sec- Cal tion 41 is inserted into the outer end of the arm 38, having its outer end split, as indicated at 41 to cooperate with the bearing portions 37 and 38 of the said arms 37 and 38. A short bolt 42 extends through and pivotally connects the three thicknesses of metal on one side of the joint thus formed, while a similar bolt 42, having a wing nut 43 thereon, extends through and pivotally connects the three thicknesses of metal on the other side of the joint.

By the construction described in connec' tionv with Figs. 1012 inclusive, the arm 38, by reason ot its pivotal support upon the bolt 39, will be free to follow the tilting movements oil the transmitter upon such bolt. The arm 37 can be adjusted in the same manner as the arm 12.

The manner of connecting the arm 37 and 38 provides an unobstructed passage for the cords 18 as well as a construction which enables the arms and the tube 41 to be conveniently and economically connected by means of ordinary short bolts, the clamping of the arms in adjusted positions being etfected by the said bolts and more particularly by the winged nut 43 and without tending to spring together the opposite sides of the two tubular arms.

Having thus described my invention, what I claim is:

1. A telephone comprising a transmitter, a receiver, a support for said receiver comprising a pair of hollow arms, one of said arms being connected to and carrying the receiver and said arms being telescopically connected, means for connecting such telescopic ends of said arms, said means comprising a tubular reinforcing member inserted within the end of the inner of such arms, a pair of bolts arranged in substantially the same axial line and each extending through the overlapping ends of the said tubular arms and the co operating portion of the tubular member therewithin, and nuts mounted on said bolts.

2. In a telephone, the combination of a transmitter, a receiver, a support for said receiver comprising a pair oi hollow arms, one of said arms being connected to and carrying the receiver, the end of one of said arms being fitted within the adjacent end of the other arm, and means pivotally connecting the said arms, the said means comprising a pair of pivotal connecting members arranged in substantially the same axial line, and each extending through overlapping ends of the said tubular arms, whereby a continuous passageway is formed through the said arms at their points of connection for the reception of a cord.

3. In a telephone, the combination of a transmitter, a receiver, a support for said receiver comprising a pair of hollow arms, one of said arms being connected to and carrying the receiver, the end of one of said arms being fitted within the adjacent end of the other arm, and means pivotally connecting the said arms, the said means comprising a pair of pivotal connecting members arranged in substantially the same axial line, and each extending through overlapping ends of the said tubular arms, one of said connecting members being provided with means for clamping the said arms in various adjusted positions,'the said connections providing a continuous passageway through the said arms at their points of connection for the reception of the cord.

In testimony whereof, I hereunto afiix my signature.
